摘　　要：随着多核处理器在计算机上的广泛使用,对于应用软件的开发来说,怎样提高软件的并行性以充分利用多核处理器的性能成为开发人员关注的热点。但是现在的并行编程技术让从未涉足并行程序开发的技术人员很头痛。尤其是对现有串行软件进行重构,不仅要对并行编程技术熟悉,还要对需重构软件的代码了解,这显然很困难且容易出错。通过对UML中活动图,状态图等并发视图的分析,发掘软件的并行性,并用并行编程模型OpenMP为UML视图搭建并行的架构,使得开发人员集中精力在具体代码的实现上。With the widespread use of multi-core processors on the computer, for the development of application software, how to improve the parallelism of software for putting fullplay of the performance of multi-core processors becomes the focus of attention of the developers. However, for those technical personnel who never set foot in the parallel program development before, existing parallel programming techniques are the big headache. In particular, to reconstruct the existing serial software, it does not only need to be familiar with the parallel programming techniques, but also to understand the software code to be reconstructed, which is obviously very difficult and is error-prone as welt. In this paper, by analysing the concurrent view of UML activity diagram and state diagram, we explore the parallelism of the software, and use parallel programming model OpenMP as the UML view to build a parallel architecture, therefore the developers are able to focus their vigour on the implementation of specific code.
